GPRS Alert
If you make a new telephone call you can interrupt an ongoing
GPRS session, for example, an incoming email. Select the check
box to get a warning in such a case.
TTY Accessory
Select the check box when you want to use the P910a together
with a TTY accessory. Teletype (TTY) accessory, text phone, is
an aid for deaf and speech-impaired people.
AoC - Call meter settings
Advice of Charge allows you to keep track of the cost of calls
and to stop the P910a from making chargeable calls when a
certain credit limit has been exceeded. The Advice of Charge
option only appears in the list if it is supported by your current
subscription.
If the credit is limited, a
Low credit warning is displayed, when
there is approximately thirty seconds of credit left. When the
credit runs out,
Credit expired is displayed and ongoing,
chargeable calls are stopped.
Please refer to the Help system for detailed information about
the Call meter settings.
Note PIN2 is required from your network operator for storing
any changes you make to the Call meter settings.
Not all networks provide charging information to the phone
during a call. If your network provides this service and your
subscription is for Advice of Charge Charging, you cannot make
or receive any chargeable calls if you are roaming in a network
that does not provide charging information.
ALS settings (subscription dependent)
Use Alternate Line Service to make calls on two lines with
separate phone numbers. Some of the phone settings are used on
a per line basis. In most cases, the settings displayed apply to the
selected line. This is then indicated in the dialog title bar. In
other cases, the lines correspond to separate settings or tabs in
the dialogs.
To set the line tags
1. Select the
ALS settings dialog.
2. Edit the names for line 1 and 2.
